Occurrence, Source, and Mobilization of Iron, Manganese, and Arsenic Pollution in Shallow Aquifer

<div>Main lithotypes and soil formations of the study area and locations of the sampling stations. The red color is for the Gangetic alluvium (<i>Ga</i>), and the green color is for the Deltaic alluvium (<i>Da</i>); the result showed that the levels of Fe and Mn are below average in the <i>Da</i> aquifer but over average in the <i>Ga</i> aquifer.</div>
